yes, and as fast as the registry updates DNS info. No-one can publish information about your DNS servers other than the registry for your domain name. Of course, DNS is heavily cached, so even if the updates are posted immediately, it will take a while for them to take effect. e.g. baremetal.info uses ns1/ns2.baremetal.com as DNS servers. The _only_ sources of information about those DNS servers are the .com registry (since baremetal.com also uses those dns servers) and the DNS servers themselves. bearmetal.com (different domain) is inside the .com registry, so the .com registry publishes the baremetal.com IP addresses, but they come from the baremetal.com 'account', as bearmetal.com has no right to publish info about baremetal.com. The exception to this is the whois system... but since that is only cosmetic, you can ignore it, or catch up with it when it is convenient. What I would do is clone your DNS servers, so that they are running on both the old and new IP addresses. Unless you only have a few domains, setting up new DNS server NAMES (e.g. ns3/ns4) is just an extra headache that won't buy you any benefits. I hope that is clear. It is amazingly simple once you get your head wrapped around it. Getting familiar with DNS query tools can be a big help... e.g. [EMAIL PROTECTED] ~/dom_ca_tools/tbr]# dig baremetal.info @tld2.ultradns.net ;; QUESTION SECTION: ;baremetal.info. IN A ;; AUTHORITY SECTION: baremetal.info. 86400 IN NS ns2.baremetal.com. baremetal.info. 86400 IN NS ns.baremetal.com. the .info DNS servers do not publish IP addresses for the baremetal.com nameservers... It slows down resolution, but anything else would be duplication of information, and a maintainance nightmare. -Tom _______________________________________________ domains-gen mailing list [email protected] http://discuss.tucows.com/mailman/listinfo/domains-gen
